Which evolutionary concept is illustrated by the similarity in bone structures of vertebrate forelimbs?
Divergent evolution is illustrated by homologous structures like vertebrate forelimbs, showing common ancestry but different functions.
Which structure in plants represents homologous organs?
Thorns of Bougainvillea and tendrils of Cucurbita are homologous structures derived from the same ancestral organ but adapted for different functions.
Which of the following statements is correct?
Darwin’s finches are a classic example of adaptive radiation, where species evolved from a common ancestor to occupy different ecological niches.
Which of the following is correct?
Hardy-Weinberg equilibrium remains stable only when no evolutionary forces are acting on a population.
Natural selection increases the frequency of beneficial traits in a population, enhancing survival and reproduction.
Which evolutionary theory emphasizes gradual changes over long periods?
Gradualism emphasizes slow and steady evolutionary changes over long periods of time.
Which of the following is incorrect?
Analogous organs have similar functions but different structures and evolutionary origins.
Genetic recombination increases, not reduces, genetic variability within populations.
Which of the following is an example of homologous structures?
Homologous structures, like mammalian forelimbs, share a common ancestry but may perform different functions.
Homologous organs share a similar structure due to common ancestry but perform different functions in various organisms.
